Detect HTML or TEXT mode for editor.

I'm work on inserting images in 'tag' form into wysiwyg editor. I need detect editor status before insert - if editor is enabled in HTML mode i want insert tag ([[...]]) else, in TEXT mode i want insert HTML (<img src="".... />).

In JS wysiwyg plugin, in invoke function is there variable data.format with editor status. Is possible check current status of editor calling some function from wysiwyg JS API? Something like:

Drupal.wysiwyg.instances[Drupal.wysiwyg.activeId].status();

would be useful.

Thanks for advice.
